摘 要 目的 研究复方蜥蜴散通过核因子κB(NF-κB)/SNAIL信号通路逆转顺铂(DDP)耐药性胃癌细胞MKN45/DDP的耐药机
制。方法 将MKN45/DDP细胞分为模型组(20%正常大鼠血清)、DDP组(1.3 μg/mL DDP+20%胎牛血清)及复方蜥蜴散低、高剂
量含药血清+DDP 组(17.2、68.8 g/kg 复方蜥蜴散的 20% 含药血清+1.3 μg/mLDDP)。测定 MKN45/DDP 细胞的生存活力、凋亡水
平、自噬水平,检测细胞上清中微管相关蛋白1轻链3(LC3)含量,检测细胞中B细胞淋巴瘤2(Bcl-2)、Bcl-2相关X蛋白(Bax)表达
水平以及磷酸化NF-κB p65 (p-NF-κB p65)、SNAIL的蛋白表达水平;利用NF-κB通路激动剂肿瘤坏死因子α(TNF-α)进一步明确
复方蜥蜴散改善DDP耐药性的分子机制。结果 与模型组及DDP组比较,复方蜥蜴散低、高剂量含药血清+DDP组细胞存活率均
显著降低(P<0.05),凋亡及自噬水平均显著升高(P<0.05);细胞中 Bcl-2(复方蜥蜴散低剂量含药血清+DDP 组除外)、p-NF-κB
p65、SNAIL蛋白表达水平均显著降低(P<0.05),LC3含量和Bax蛋白表达水平均显著升高(P<0.05)。复方蜥蜴散高剂量含药血
清+DDP可有效逆转TNF-α诱导的耐药细胞中LC3Ⅱ/LC3Ⅰ比值下降及Bax蛋白表达下调(P<0.05)。结论 复方蜥蜴散含药血
清联合DDP可通过抑制NF-κB/SNAIL信号通路,诱导MKN45/DDP细胞凋亡及自噬性死亡,从而逆转该细胞的DDP耐药性。

ABSTRACT OBJECTIVE To study the mechanism of Compound lizard powder on reversing cisplatin(DDP) resistance in
resistant gastric cancer cell MKN45/DDP through nuclear factor-κB (NF-κB)/SNAIL signaling pathway. METHODS MKN45/DDP
cells were divided into model group (20% normal rat serum), DDP group (1.3 μg/mL DDP+20% fetal bovine serum) and
Compound lizard powder low- and high-dose drug-containing serum+DDP groups (17.2, 68.8 g/kg Compound lizard powder 20%
drug-containing serum+1.3 μg/mL DDP). The viability, apoptosis and intracellular autophagosome of MKN45/DDP cells were
detected. The content of microtubule-associated protein 1 light chain 3 (LC3) in the cell supernatant was detected. The expressions
of B-cell lymphoma 2 (Bcl-2), Bcl-2-related X protein (Bax), as well as the protein expression levels of phosphorylated NF-κB
p65 (p-NF-κB p65) and SNAIL were detected. The molecular mechanism of Compound lizard powder in improving DDP resistance
was further clarified by using NF-κB pathway agonist tumor necrosis factor-α (TNF-α). RESULTS Compared with model group
and DDP group, the cell survival rates of Compound lizard powder low- and high-dose drug-containing serum+DDP groups were
significantly decreased (P<0.05), while the levels of apoptosis and autophagic death were significantly increased (P<0.05). The
expression levels of Bcl-2 (except for the compound lizard powder low-dose drug-containing serum+DDP group), p-NF-κB p65
and SNAIL protein in MKN45/DDP cells were significantly decreased (P<0.05). The content of LC3 and expression of Bax
protein were significantly increased (P<0.05). High-dose Compound lizard powder drug-containing serum+DDP could effectively
reverse the down-regulation of LC3 Ⅱ/LC3 Ⅰ and Bax protein expression induced by TNF- α (P<0.05). CONCLUSIONS
Compound lizard powder drug-containing serum combined with DDP can induce apoptosis and autophagic death of MKN45/DDP
cells by inhibiting NF-κB/SNAIL signaling pathway, thus
